Hi, I have a problem with my RNS-e. The phone is on all the time and I cannot reset. Its as if I am on the phone and the radio cuts out. I disconnected the Kafatec Fiscon as I thought this was causing the problem. This is still disconnected I disconnected the RNS-e, power it down and also reset it. But the problem is still there. I retrofited the RNS-e 4 years ago and had no problems up till now. My battery failed this week and I replaced it yesterday. Does anyone have any ideas why this is happening?
